So I am rigging a character with the help of Advanced Skeleton to take it to Unity, and the facial rig is done with the mixed (Joints plus Blend Shapes) option. So while exporting the rig with the help of export options within the plugin, i.e. 'FBX export' The body, eyes, teeth, and hair geometries that have the Blend Shapes node do not export, and the rest of them, which are cloth and shoe geometry, export as they do not have the Blend Shapes node. So if anyone has any solution to this issue, please provide me with a solution.
